Ugh. That's awful. It's pretty obvious where he gets it.
On the plus side you know your mom is helpful and you have that to look forward too. Hopefully your H being away helps your relationship. I really think if mine went away it would help. I've seriously been considering asking him to stay at his moms for a week or so because I might like him more then. Last night he decided when he got home was a great time to have a [email protected] convo about pacifiers. First time in days I've actually been asleep and he wakes me up.
I hope things get better w your MIL before she leave. Like now would be great for you
